TOKYO (Kyodo) -- An earthquake registering a preliminary magnitude 7.1 struck off the coast of Fukushima Prefecture early Saturday morning and the Japan Meteorological Agency issued an alert for tsunami of 1 meter high for Japan's northeastern Pacific coast but lifted it about two hours later.

The agency urged people to stay away from waterfront areas after the 2:10 a.m. quake. The tsunami alert covered Iwate, Miyagi, Fukushima, Ibaraki and Chiba prefectures. It was lifted at 4:05 a.m.

A woman in her 60s in Miyako, Iwate Prefecture, fell from her bed and hit her head and back, according to firefighters. She sustained minor injuries and was transported to a hospital.

No abnormality was reported at the Fukushima Daiichi nuclear power plant, which was crippled by the magnitude 9.0 quake in March 2011, according to Tokyo Electric Power Co. Workers, however, were ordered to evacuate from waterfront.

Tohoku Electric Power Co. said no abnormality has been confirmed at its Onagawa nuclear power plant.

Evacuation advisory was issued for coastal residents in Higashimatsushima, Miyagi Prefecture, Ofunato, Kamaishi, Rikuzentakata and Iwaizumi in Iwate Prefecture.

The agency said 40 centimeter high waves were observed in Kuji Port, Iwate Prefecture and Soma, Fukushima Prefecture. It also reported 30 cm waves in Ishinomaki, Miyagi Prefecture, and 20 cm waves in Ofunato in Iwate.

The focus was roughly 10 kilometers underground in the Pacific Ocean around 290 kilometers east-southeast of Oshika Peninsula, the agency said.

The quake registered a moderate intensity of 4 on the Japanese seismic scale of 7 in Fukushima, Miyagi, Ibaraki and Tochigi prefectures. Tokyo marked intensity 3.

The agency revised the magnitude to 7.1 from 6.8. It said the latest quake is an aftershock of the 2011 quake, which triggered massive tsunami and caused nuclear meltdowns at the Fukushima Daiichi plant.
